Research expertise: Cyber-security and privacy in the Smart Grid, privacy of electronic data, information- theoretic privacy measures, applications of game theory to privacy problems, finite block-length source coding, distributed state estimation and optimal power flow with security and privacy guarantees in the Smart Grid

Lalitha Sankar received a bachelor’s degree in engineering physics from the Indian Institute of Technology, Bombay, in 1992, a master’s degree in electrical engineering from the University of Maryland in 1994 and a Ph.D. in electrical engineering from Rutgers University in 2007. From 2010-2012, she was an associate research scholar at Princeton University. From 2007-2010, Sankar was a postdoctoral fellow supported by the Princeton University Council on Science and Technology. Prior to her doctoral studies, she was a senior member of technical staff at AT&T Shannon Laboratories from 1995-2002. She received the NSF CAREER Award in January 2014, and an academic excellence award from Rutgers in 2008. She is also the lead PI on a $1.4M 4-year NSF grant on cybersecurity of the electric power system.
